Chlorophyll

Also indexed as: Chlorella, Wheat Grass

What is it?

Chlorophyll is the substance responsible for the green colour in plants that accomplishes photosynthesis.

Chlorophyll has been used traditionally to improve bad breath, as well as to reduce the odours of urine, faeces, and infected wounds. Chlorophyll has anti-inflammatory, antioxidant, and wound-healing properties.¹ ²

Historically, chlorophyll was used for gastrointestinal problems, such as constipation, and to stimulate blood cell formation in anaemia. Some preliminary evidence suggests that chlorophyll might help detoxify cancer-promoting substances.³ ⁴

Where is it found?

Good dietary sources of chlorophyll include dark green leafy vegetables, algae (including spirulina and chlorella), wheat grass, and barley grass. Supplements of chlorophyll as powder, capsules, tablets, and drinks are also available.

Chlorophyll has been used in connection with the following conditions (refer to the individual health concern for complete information):

Science Ratings

Health Concerns

Fibromyalgia

Constipation

Halitosis (bad breath)

Reliable and relatively consistent scientific data showing a substantial health benefit.
2Stars

Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1Star

For a herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.

Who is likely to be deficient?

Because chlorophyll is not known to be an essential nutrient, a deficiency does not exist. People who do not eat plenty of green foods lack chlorophyll in their diets.

How much is usually taken?

Optimal levels remain unknown. Chlorophyll in the amount of 100 mg two or three times per day can be used to treat bad breath.

Are there any side effects or interactions?

No side effects have been reported with the use of chlorophyll.

At the time of writing, there were no well-known drug interactions with chlorophyll.
